1,153,156. Specification of Application filed May 20,

To all whomit may concern: 7

Be it known that I, EDWARD FULLER, Jr,

a citizen of the United States, residing at Altheimer, in the county of Jefferson and I State of Arkansas, have invented certain new and useful Improvements in Stoker's for Locomotive-Boilers and the like, of which the following is a specification.

My invention relates to improvements in stokers for steam boilers, such as the boiler of a railway locomotive, ship, or other stationary boiler.

The invention aims to provide a stoker A which will operate in a highly satisfactory manner, to feed the fuel or coal to the boiler, as desired, and which may be controlled in its operation by a single attendant.

A further object of the invention is to provide a power driven stoker of the above mentioned character, which is so constructed in the event that the same should become inoperative, the coal or other fuel may be man ually removed therefrom in convenient manner. 7

A further object of the invention is to provide apparatus of the above mentioned character, which is simple in construction, inexpensive to manufacture, and may be installed upon a railway locomotive or the like without material alteration thereto.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of apparatus embodying my invention, Fig. 2 is a similar view of the opposite side thereof, Fig. 3 is a plan viewof the same, Fig. v4: is an end elevation of the same, Fig. 5 is a central longitudinal sectional view through the apparatus, and, Fig. 6 is a transverse sectional view takenzon' line 6.6 of Fig. 2. v

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a tender of a railway locomotive (the invention being illustrated as applied to a railway locomotive but of course not restricted solely to such use), within which is arranged a longitudinally extending coal or Lettersr t n Patented Sept. 7', 1915 1914.

fuel; receiving casing 11, having a vertically inclined bottomior wall 12.

The casing 11 forms'with the shell of the tender 10 ayspace 13 for receiving water, supplied thereto by. any suitable means, and adapted to be withdrawn therefrom and supplied totheboiler when needed. The fuel receiving casing 11 is provided near its outlet end with upstanding for a purposeto bedescribed, and longitudinal extensions 15, iformingwith the in-v clined bottom or wall 12 an outlet chute 16, as more clearly illustrated in Fig. 6. As more clearly shown in Fig. 2, the outlet chute 16 is arranged to supplr the coal or the. like through an opening17,leading into the fire-box of a boiler 18.

The upper side of the chute 16 is normally closed by a vertically swinging lid or cover 19, hi'nged at 20, which. isadapted when swung upwardly to be engaged-and portions 14,

held the open position by a vertically swinging approximately. .U-shaped holderbracket 21, pivoted at 22.

The numeral 28 designates vertical guide rods, arranged upon opposite sides of the opening 17 of the fire-box and receiving thereon slidably eye-bolts 24:, carried by and pivoted to a vertically movable door 25. The door 25 is adapted when not in use to rest upon the cover or lid 19, but when the cover or lid is not in use the door 25 is employed to open and close the opening 17, as is obvious.

-The numeral 26 designates. a horizontal rock-shaft, having portions 27 and 28 journaled through the vertical extension 14. This crank-shaft is provided with an inner crank 29, having pivotal connection with the upper end ofa vertically movable combined agitatorand cut off member or valve 30, as shownat 31. The member 30' is arranged inwardly of and adjacent the inlet end of the chute 16 and is provided upon its inner side :with agitator fingers' 32, rigidly secured thereto.

embodying radially extending arms 38. This rotatable'feeder is splined upon a horizontal. rotatable shaft 39, journaled through vertically adjustable bearings 40, adapted to be locked in adjustment in vertical positions by nuts 40. It is thus seen that the shaft 39 may be removed from the chute 16, by a longitudinal movement thereof, whereby element 37 may also be removed, thus permitting the coal to be removed therefrom by means of a shovel or the like.

The shaft 39 is driven by a sprocket wheel 40, splined thereon, engaged by a sprocket chain 41, in turn engaging a sprocket wheel 42, ri idly mounted upon the rotatable shaft 36. second sprocket wheel 43'is rigidly mounted upon the shaft 36, and engaged by a. sprocket chain 44, engaging a sprocket wheel 45.

The numeral 46 designates a prime mover, preferably a steam engine of the vertical type, embodying a crank-shaft 47 which rotates the sprocket wheel 45. The operation of the steam engine may be controlled by a throttle lever 48, as shown.

The operation of the apparatus is as follows :'lVhen the engine46 is operating, the

sprocket wheels are rotated. The pitman 34 is reciprocated, to turn the rock-shaft 26 in opposite directions, whereby crank 29 will raise and lower member 30. This member together with fingers 32 will agitate the coal within the casing 11, said member 30 permitting a desired amount of the coal to pass below the same upon its upward movement and cutting off the supply of the same upon its downward movement. The feeder 37 is continuously rotated during this operation, whereby the coal supplied into the chute 16 will be discharged therefrom through opening 17 into the fire-box of the boiler. The operation of the engine may be stopped by manipulation of the throttle lever 48. In the event that the apparatus should become inoperative, the lid or cover 19 is swung to the upper open position and retained in such position by the holder bracket 21. The door 25 may be opened, whereby coal may be shoveled from the chute 16, the member 30, being retained in the open position, and the member 37 removed as stated.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the b0 adjacent opposite sides of the opening,

a movable door adapted to cover and uncover the fire-box opening, elements attached to the movable door and having sliding engagement with the approximately vertically arranged rods, and means to supply material to the chute.

2. In apparatus of the character described, a fuel holding receptacle having a longitudinally inclined bottom wall and an outlet chute adjacent the lower end of the inclined bottom wall with the end wall of the receptacle adjacent said chute extending substantially vertically above it for a substantial distance, a plate arranged within the receptacle inwardly of and adjacent the substan tially vertical end wall of the receptacle to engage therewith and with the bottom wall ofthe receptacle, a plurality of approximately horizontal agitator members secured to the plate and extending inwardly beyond the same fora substantial distance, a substantially horizontal rock-shaft arranged inwardly of the plate and connected with the receptacle and provided with an inner crank portion pivotally connected with the upper end of the plate and provided near one end with a crank, a rotatable shaft provided with the crank, a pitman pivotally connecting said cranks, a rotatable feeding element disposed within the chute in advance of said plate, driving connecting means between the rotatable feeding element and the rotatable shaft, and means to rotate the rotatable shaft.

In testimony whereof I afiix my-signature in presence of two witnesses.
